I do drink more, especially since kegging. Before I brewed, I didn't drink at all during the week, or at least very rarely. When I bottled, I may have 1-3 during the week. Now I'm up to 3-5 during the week, though usually 10oz pours. Weekend consumption has stayed about the same.
Having one beer a night I don't see as trying to catch a buzz, I view it as selecting the beverage currently available that taste the best to me. No different than selecting a can of soda over ice tea. Doctors may disagree with me.
